T all wle/bm, it may concern;

Be it known that I, EDWARD J. ROCHE, of

v Milford, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements lin Machines for Comminuting Bone and VegetableMatter, of which the following is a specification.

Thls invention relates to an improvement in machines for comminuting bone and vegetable matter for live-stock feed.

The invention has in view' the provision of a machine of this character which will do more effective work than any'heretofore devised, and in which the feed will b e automatic, and adapted to be checked when it becomesexcessp iv'eand also adapted to be discontinued altogether at a predetermined point.

To the above ends the invention may be said to consistin the novel features of construction and combinations of parts .which are fully described hereinafter `and recited in the claims.

The accompanying drawings illustrate a machine embodying the invention.

Figure 1 shows a side elevation of the machine. Fig. 2 shows a longitudinal section of means for frictionally connecting` the feedscrew and cutter. Fig. 3 shows a rear elevar tion of the rotary cutter and of the cylinders which hold the material. Fig. 4 shows a front elevation of the rotary cutter, the means for frictionally connecting the feed-screw and cutter being omitted. Fig. 5 showsa sectional detail of the front end of one ofthe cylinders and a portion of the rotary cutter. Figs. 6 and -show details of one of the cutting knives. Fig. 8 shows a top plan view of the machine. Fig. 9 shows a plan view of.` parts appearing at the left of Fig. 8, under a different adjustment than they appear in 'said Fig. 8. Fig. lO shows a sectional detail illustrative of a separable nut for engaging the feed-screw.

Fig. 11 shows a detail sido view of the cam controlling the vseparable nut.

The same letters of reference indicate the same parts in allthe figures.

The letteradesignates thesupporting frame of the machine on which are mounted, sideby-side, a pair of horizontal cylinders,fb, for containing the material to be treated, the said cylinders having hinged covers, b', for admitting` the material. A circular disk, c, is supported in bearings on the frame, a, between the two cylinders, and the saidV disk extends surface of the disk, and the other, c2, being fastened over the blade, c', having a toothed or serrated cutting section, c3. The object of ythis peculiar construction` of `the cutting knives is to prevent the machine from delivering the material in slices. The blade, c,is calculated to slice or shave the material, and the teeth of the blade, c2, to divide these slices or shavings so that the material will be delivered in small particles, as desired. Bolts,

c4, fasten the blades together and to the disk, and screws, c5, provide means for adjusting them.

The disk, c, is provided with an elongated hub which is here shown as a separate sleeve, d, littingthrough a boss, d', formed at the center of the disk, and preventedfro'm turning therein by screws, d2. 'A feed-screw, e, eX- tends through the sleeveyd, and projects from the front end thereof, andthe said screw is designed to be frictionally connected with the rotary disk, c, through the following means.

The sleeve, d, has a conical socket, e,'formed in its inner end and a conical block, e2, affixed to the screw, e, engages said socket. A circular block, e3, is tted over the front end of the screw, e, and is formed to squarely abut the boss, d', and a friction ring, e4, is fitted in the block, e3, so as tobear against the end of the sleeve, d. The block, e3, may be moved longitudinally of the feed-screw. A handwheel, f, engages screw-threads of the feedscrew, and is formed with a collar which emwhile the friction ring, e4 is 'pressed against the front endof said sleeve. In this manner parts thus avoided. The feed can be disconi nected whenever desired by operating the hand-wheel f. l

Followers, g, t the bores of the cylinders, b, and are designed to feed the material therein to the rotary cutter, and bars, g', con-` nected with said followers are themselves connected together by a cross-head or frame, g2, l

which carries a nut for engaging the feedscrew, the latter extending loosely through the frame, g2. The said nut is made in two parts, h, which are pivoted to the cross-head, gg, SO that the nut can be opened and closed todisengage it from and engage it with the feed-screw. The members, h, of the nut are formed with rounded arms, h', which extend Lthrough slots, h2 of a plate, h3, pivoted to the cross-head, g2, said slots beinglocated on opposite sides ,0f the pivot. This plate, h3, constitutes ,a .Gsm Wlliil when turned in one direction QlOses the nuff, and when turned in the opposite direction opens the same by the action of the sides of the slots, h2, on the arms, h. This cam is adapted to be turned by hand, when desired, and is also adapted to be automatically actuated to open the nut when the fQllQWers have advanced to the limit 0f their IDQVG.' ment. This is accomplished by means of a lever, z', pivoted at one end to the cross-head, g2, and extending in front of the cam, h3, and when the nut is closed on the feedfscrew, the upper end of the cam is in its forward position. The lever, z', has a foot, i', which When the followers reach the limit of their forward movement abuts one of the cylinders, d, or any other suitable fixed portion of the machine, and the lever is moved back, and coming against the cam, h3, causes the same to throw the nut open, and thus disengage it from the feed-screw and stop the feed.

The means here shown for driving the machine consists in a gear, j, formed on the disk, c, a pinion, j', meshing with said gear, and supported in a fixed bearing on the machine frame and a ily-wheeLjz, on the journal of said pinion and provided with a handle, ji. After the separable nut has been opened the followers can be quickly drawn back by hand to position for starting, they being disco11- nected from the feed-screw.

While the machine here shown has been designed for cutting up green bones and vegetable matter, it may be employed for other purposes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a holder for the material, a rotary cutter working across said holder, a follower to feed the material in the holder, a feed-screw for advancing said follower, and means for frictionally connecting the feedscrew with the rotary cutter.

2. The combination of a holder for the material, a rotary cutter working across said holder, a follower to feed the material in the holder, a feed-screw for advancing said follower, means for frictionally connecting the said screw and the rotary cutter by a longitudinal movement of the screw, and means for moving the screw into such engagement with the disk.

3. The combination of a holder for the material, a rotary cutter working across said holder, a follower to feed the material in the holder, a feed'screw for advancing the follower, a friction cone clutch for operatively connecting the rotary cutter and the feedscrew by longitudinal movement of the lat ter, and means for producing such movement of the screw.

4E. The combination ef a holder for the material, a rotary cutter working across said holder and having an elongated hub, a follower to feed the material in the holder, a feedscrew for advancing said follower, said screw extending through thehub of the cutter and provided with friction devices adapted t0 .engage the said hub at opposite ends, one being xed 0n the shaft and the other longitudinally movable thereon, and a handle screwing on said shaft and engaging the 10ngitudnally movable friction device so as to move it longitudinally but free to turn independently thereof.

5. The combination of .a .holder for the material, a rotary cutter working across said holder, a feed-screw adapted to be rotatively connected with said cutter, a follower for feeding the material in the holder, a separable nut carried by said follower and engaging the feed-screw, and a cam for opening the same and adapted to be actuated at a prede termined point in the followers advance.

6. The combination of a holder for the material, a rotary cutter working across said holder, a feed-screw adapted to be rotatively connected with said cutter, a follower for feeding the material in the holder, a separable nut carried by said follower and engaging the feed-screw, a cam for opening the same, and a lever for operating the cam and adapted to abut a fixed part ofthe machine whereby it is actuated.
